Biography

Dong-Hoon Choi received the B.S. degree in electrical and electronic engineering from Yonsei University, Seoul, Korea, in 2007, and the M.S. and Ph.D. degrees in electrical engineering from the Korea Advanced Institute of Science and Technology, Daejeon, Korea, in 2009 and 2014, respectively. 
During his Ph.D. course, he worked on a columnar nanoporous membrane. He proposed and demonstrated for the first time that a generally sputtered thin film can be exploited as a versatile nanosieve. His related works were published in Advanced Materials and at the IEEE International Conference on Nanotechnology in 2010. His work published in Advanced Materials was selected as a cover picture. Also, he invented and demonstrated a new type of liquid-based electrostatic energy harvester for human physical movements, and related works were published in Smart Materials and Structures, and at the International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Application in 2010. 
He is currently a Post-Doctoral Research Fellow with the Institute for NanoBioTechnology, Johns Hopkins University. His current research interests include electrochemical biosensors, nanoporous membranes, RF tunable microelectromechanical systems devices, and energy harvesters.
